ARTHUR E. SMALL, or CHICAGO, ILLINOIS, ASSIGNOR TO UNION METAL rnonoccrs COM- PATENT OFFICE PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE METALLIC-PLATE WALL ELEMENT Application filed August 9, 1928. Serial N'o. 298,574.

The invention relates to railway freight train cars and more particularly to metallic plate walls therefor, and consists in forming an integral strut-beam adjacent one side margin of a metallic plate which is capable of sustaining considerable compressive forces longitudinally of its length (as a column), and also capable of sustaining forces normal to its length (as a beam), Such a construction eliminates the beam and/or post which is usually attached to one or more margins of a metallic plate when used as a wall.

Such a construction when used in house or roofed cars (such as box, automobile, stock, etc.,) would eliminate the use of corner post or door post, or if the strut-beam is positioned horizontally, would eliminate the use of theend plate or end sill. \Vhen used in opentop cars (gondolas) the corner 2 post could be dispensed with.

A further object of the invention is to pro-- vide such a metallic plate with integral corrugations which vary in length according to the formation of the integral strut-beam. i A further object is to so form the integral strut-beam so as to provide means of securing the nailing strip for the lining of the car.

Another object is to provide a metallic wall-of a railway car-with a specific form of integral flange, which flange performs the usual function of the corner post, door post,

end plate or end sill In the drawings r Figure 1 shows a railway .loox .car equipped with atypical application of my device. Figure 2 is a side elevation of Figure 1. Figure 3 is a section on line 33 of Figure 1.'

Figure 4 is a section ure1.'

Figureo is a perspective view of a metallic plate with one margin formed into an integral strut-beam according to my in vention.

of a railway car.

on line H of Fig- In Figures 1-4, inclusive, theflconstruction is shown when used in a metallic end wall for a railway box car. The metallic plateis bent to form a straight flange 2 adjacent the central portion of the vertical margin of the end wall, preferably adjacent the intermediate longitudinal frame mem bers 3 7 (if any) of the car to which it is 1 preferably secured by means of the straps 4 of Figure 2. This straight flange changes to a Z shaped flange 51l12 at the upper I and lower part of the endwall preferably tudinal frame members (side plate and side sill respectively) of the car, to which members it is preferably secured by the gussets or straps 8+9. Securing means 10 also prefvery strong column to resist compression and torsional stresses and also provides a very strong beam, restrained at its oppo site ends, to resist horizontal forces, in either direction, i. e. arallel with either the side or end wallsof t e car, therefore, I call the structure an integral strut-beam.

If desired the filler 13 may be used and secured-to the strut-beam by the bolts 14 so 1 adjacent the upper (6) andlower (7) longithat the filler reinforces the strut-beam both I as a column and as a beam. It 18 well known in the art of car designingto corrugate a wall to enable it tolbetter withstand or resist the stresses which exist in such a wall (see patents to Murphy- Sisson, 1,021,571, July 2, 1912 and A. Er. Small, 1,638,17 2, August 9, 1927) but I preferably vary'the length of such corrugations according to. the formation of the strutbeam. 7 V p a The corrugations are made as long as" possible and terminate into metallic plate adjacent the flange forming the strut-beam, leaving only a small portion (1819) between the end of thecorrugation and its supporting flange, therefore, the corrugations 17 which terminate adjacent the straight flange (2) portion of the strut-beam are longer than the corrugations 16 which terminate adjacent the Z section (11) thereof.

A corrugation is a beam and must terminate adjacent its supports so as to transmit its loads thereto.

The nailing strips 21 provide means of attachment for the usual lining boards 22 and are attached to the strut-beam at the upper and lower 2 sections, respectively, preferably to the web portion 5 by bolts 23 and also preferably to the outer flanges 12 thereof by bolts 24. These bolts prevent the nailing strip from twisting and otherwise getting out of place. The sheathing 25 is nailed to the nailing strip.

Figure 6 is a perspective view of a metallic plate with one margin formed into a strutbeam comprising a straight flange 2 forming :L'an angular section adjacent the vertical center of the margin which gradually changes into a Z shaped section (5-11-42) atboth the upper and lower parts of the margin of the plate. The longer corruga tions 17 and the relatively shorter corrugations 16 are also shown. the web portion 26 may conditions.

The drawings illustrate the preferred The obliquity of be varied to suit form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the .claims will occur to persons skilled in the art.
